SPECIFICATION forming part of Letters Patent No. 422,615, dated March 4., 1890.

Application filed August 24, 1888. Serial No. 283,690. (No model.)

To all whom it may concern:

Be it known that we, RICHARD O. NUGENT and SIMON H. STUPAKOFF, citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Iniprovem cuts in Machines for Flan gin g and Nozzling Metal Plates and Boiler-Heads; and we do hereby declarethe following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompany ing drawings, which form a part of this speci-' fication, in which-- Figure 1 is a side elevation, partly in section;

Fig. 2, an end view; Fig. 3, a plan; Fig. 4, a11- enlarged'vertical central section of the main and pressure shafts. Fig. 5 is a top plan of the fianging-roll, the eccentric crank-pin, and

the eccentric sleeve inclosing the same. Figs.

, ure shafts, showing the pinion upon the pressure-shaft projecting through the orifice in the main shaft to enable the same to engage the inside gear of the shell which surrounds both shafts. Fig. 10 is a sectional perspective of the shell broken away to show the inside gear and the spirally-inclined projections upon the inside surface of the same. Fig. 11 indicates a sectional perspective of the shell and main shaft, the shell being broken away to show the spirally-inclined projection with its downwardly-extending lug uponthe inside surface of said shell, and also the corresponding proj ection upon the outside surface of the main shaft. Fig. 12 indicates a side elevation on an enlarged scale, partly in section, of the flan ging-inachine below the plane of the table. Fig. 13 shows a reduced side elevationof the frame to which said levers are secured, also side view of a device upon said frame adapted showing the nut-housing.

of Fig. 15.

Fig. 9 is a cross-section to lock said levers when adjusted. Fig. 14 is a detail sectional view on an enlarged scale,

Fig. 15 is an enlarged view, in side elevation, of the means for locking the operating-lever D; and Fig.

16 is a detail sectional view on the line 3 3 'In the drawings, A is an iron table supported on legs B B, and provided with 001- umns C O, which are connected by the headpiece D and support the iron girders E E.

F is the housing of the nut G, said nut havin g abeveled gear-wheel Hand Worm-wheel I. J is a smaller beveled gear-wheel secured to the horizontal shaft K, which is journaled in the bearing M. (Shown in the dlawings as being part of nut-housing F.) The outer end of said shaft K is provided with the handwheel L.

N is a WOlDl secured to the horizontal shaft 0, or forming part thereof, which engages in the wornr wheel part of the nut G.

P is a hand-wheel fastened to the end of said shaft 0, and Q a bearing of the same. (Shown in the drawingsas being part of the nut-housing F, which, however, and also the bearing M heretofore referred to, may be formed of separate pieces suitably attached in their respective positions.) The front bearing of the shaft 0 is not shown in the drawings in order that a better'view of the parts lying behind it may be had.

In Fig. 16 of the drawings we have illustrated tubular extension or sleeve, which ,is suitably supported or journaled in the stationary housing in such a manner that the nut can be rotated on its axis when either shaft 0 or K is rotated, and the interior of this tubular extension or sleeve is provided with threads with which engage the vertically movable feed-screw R, which carries the presser-foot.

R is screw provided with one or more longitudinal grooves for the reception of one or more splines or keys S, secured to the headpiece of the nut-housing to prevent the screw revolving around its axis.

T is the presser-foot of said screw, and U is a removable ring fastened within the same by screws. (Not shown.)

V is a boiler-head, and \V the upturned flange of the nozzle of the same.

X is a removable ring inserted into the central cavity of the table, suitably secured therein, and forming the head-piece thereof.

Y is a loose pulley on the horizontal driving-shaft 1, and Z a driving-pulley on the same.

a is a standard, on the top of which is the end bearing of said shaft.

1) is a hanger secured to the table, provided with a second bearing for said shaft.

0 is a small beveled gear-wheel fastened to said shaft, which engages the large beveled gear-wheel d, secured to the vertical main shaft 2.

c is a gear-wheel rigidly fastened to said vertical main shaft, and f is a second gearwheel which fits loosely upon the same, so as to permit it to revolve independent of said shaft, and is supported by the ring or collar g. For convenience we have designated the gearsj u st referred to as the main and back gear, respectively, and the gear-wheels h and i, which are secured to the intermediate shaft 3 and mesh with said main and back gear, as the intermediate gear.

k is the top bearing of said intermediate shaft, being apart of the hanger b, or it may be formed of a separate piece rigidly secured thereto or to the table, and Z is the foot-bearing of the same. m is a series of spaeedprojections forming a clutch on the bottom of the back gear-wheel, and n is a clutch on the top of the shell 0, corresponding with the same. The inside surface of said shell 0 is provided with teeth 13, which engage in teeth of a pinion on the pressure-shaf t, as indicated in Figs. 1, 4, and 10.

p and q are respectively female and male parts of a fliCtlO1l-Oll1fCl1.

r is a lug or extension on the main shaft, which, when in proper position, engages a corresponding lug 8 within the shell of the inside gear, which thereby forms a third clutch. According to their functions and for the purpose of conveniently designating them, we call these three clutches the back-gear, the stationary, and the mainshaft clutch, respectively.

If f are two annular rings, and u is an annular groove between them around the shell, which guides the rollers or their equivalent mechanism carried by the inner end of the bell-crank lever A, which lever is pivoted to the upper end of the stationary frame or sup port 13. This bell-crank lever has its other free end connected to a link 0', which serves to connect said lever A to the vertical operating-leverD, which is pivoted or fulcrumed near its lower end to a frame E. This vertical hand-operating lever D carries a catchrod F, which is supported in suitable guides on the lever D, so as to be free to move endwise vertically thereon, and this catch-rod is normally depressed by a coiled spring G, which is fitted around the catch-rod near its lower extremity and between lugs or cars on a fixed plate carried by the leverD, as shown in Figs. 12, 15, and 16. The lower extremity of the catch-rod is provided with a laterallyextending lug F which fits and operates in a segmental guide It on the inner side of a horizontal lover or link H, this connection between said horizontal lever II and the catch-rod being such that the lateral lug F of the catch-rod serves to elevate the inner end of the lever or link ll, when the catchrod F is lifted vertically by operating its hand-piece at the upper extremity of the levei' D, the vertical play or movement of the catch-rod and horizontal lever or link H being effected without moving the hand-lever D on its pivot. H is pivoted at its outer end to the upper outer end of the frame E, and the segmental guide h on said lever H is of less length and convexity than the are of a circle described by the lug F when the lever D is moved on its pivot or fulcrum, so that when the lever is thrown rearward, for a purpose hereinafter explained, the lug F on the catch-rod will become disengaged from the segmental guide h 011 the horizontal lover or link II, this disengagement of the catch-rod and lover ll being effected after the lever H has been operated to clutch the drivingpulley Y to the shaft 1.

The inner end of the horizontal lover or link H is attached to a vertical link I, which is pivoted to the horizontal arm of a bellcrank lever J the other arm of the lever J being connected to an endwise-movable shifting-rod K, the free end of said shifting-rod being attached to a ring L, which fits loosely around a sliding collar M fitted on the driving-shaft 1, so as to slide freely thereon alimited distance, this movement of the collar being controlled by the rod K The sliding collar carries a clutch rod or bar N, which projects beyond the collar, and said bar or red is adapted when the collar is forced forward by the rod to fit into a slot in the shaft and pulley Y, as shown in Fig. 1.2, in order to connect or secure said pulley rigidly upon said shaft.

When the lever or link II is elevated in the manner described and operated to clutch the driving-pulley to the shaft, said link or lever is held in its elevated position by means of a locking device or latch O, which is thrown automatically beneath the lever or link when it is raised, whereby the lever D is free to move on its fulcrum, as the projection F of the catch-rod is disengaged from the lever or link ll, and the latter is held in its stationary position in order to keep the pulley Y clutched to the shaft. This locking device consists of a vertical arm 0', which is pivoted at its lower end to standard or frame E, and the upper end of the arm has a projection or hook which is adapted to take be- The horizontal lever or link IIO v notch or notches Q, into which the lower end of the catch-rod F is adapted to take or fit when said rod is depressed by its spring, in.

order to hold the vertical handoperatinglever D in position and prevent the same from moving on its fulcrum.

4 is a vertical pressure-shaft journaled ec-' centrically in the vertical main shaft, the u pper end of which above the flange or disk 6 terminates in an eccentric or crank pin 5, of polygonal cross-section.

7 is an eccentric sleeve fitted to and slipped over the crank-pin, and 8 is an interchangea blefianging-roll provided withspiral grooves, as shown in, Fig. 8%, said fianging-roll resting on the friction-rollers 9 9 of the crankdisk 6 and, fitted upon the eccentric sleeve in. such manner that it may freely revolve thereon. r

10 is apinion secured upon the pressureshaft, the teeth of which project through an orifice in the main shaft and engage the corresponding teeth 13 of the inside gear of the shell, as indicated in Figs. 1, 4E, and 10.

12 is the top bearing of the vertical main shaft, which is provided at the center of the table A and depressed below the plane of the top surface thereof, as shown in. Fig. 12, the upper end of said hollow main shaft being provided with an annular flange 12, that bears on the top of the upper bearing; and 16 is.

the foot-bearing of the said hollow main shaft.

In the practice of our invention the rotary motion of the inside or pressure shaft is somewhat more or less. rapid than that of the main shaft inclosing it. The end is secured by providing the back gear-wheel on said main shaft with a greater or less number of teeth than the main gear-wheel upon the same shaft. We have secured very good results by increasing the speed of the pressure-shaft by constructing said back and main gears with one hundred and fourteen and one hun-.

dred and fifteen teeth, respectively, and the inside gear of the shell and the pinion upon overhead clamping device, will protrude through one of said apertures 1n the plate,

therebycentering the same upon the table, the pressure-foot of the overhead piece or clamping device being quickly lowered by turning the hand-wheel L, attached to the shaft K, which operates the beveled gear J, which forms part of the pressure-nut. T n;- mediately the pressure-foot of the clamping device impinges upon the surface of the plate an additional and powerful pressure may be applied by throwing the worm N into gearv with the worm-wheel I of the nut and turning the hand-wheel P, attached to the end of the shaft 0, which operates said worm. The operator in charge now operates the vertically-movable. catch-rod F to clutch the driving-pulley Y to the shaft 1, which is accomplished by lifting the catch-rod vertically, so that its lateral stud F raises the inner end of the horizontal lever or link H, thus turning the bell-crank lever J to force the shiftingrod K forward, whereby the sliding collar M is moved to force the clutch bar or rod N into the slot on the shaft and driving-pulley, thus rigidly connecting said parts, the lever or link H being held in its elevated position by the spring-pressed locking-arm O, which takes beneath the lever or link as soonas it is elevated. The hand-lever D can now be moved backward to operate the link 0 and bell-crank lever A in order to lift the vertically-movable shell, and as the lever is turned 011 its fulcrum the pin or lug F on the catchrod isdisengaged from the segmental guide h on the horizontal lever or link H by reason of said segmental guide being curved eccentric and of less length than the arc of a circle described by the lug F when the lever D is moved on its fulcrum, as before explained. Y

The lever H islocked by the locking-arm to hold the driving-pulley clutched to the shaft 1, and, the lever D being free from the lever H, it can be moved 011 its pivot, as explained, to lift the shell sufficient to enable the clutchcon the top thereof to engage the corresponding clutch on them ain gear-wheel,

ICO

after which said lever D is locked in position by the lateral projection F on the catchrod F, fitting in one of the notchesQ on the top of the frame E. The two operating-levers H D being thus locked in position, and

the shell having converted the loose pulley.

into a driving-pulley, power is applied to impart rotary motion to the main shaft 2 from the horizontal driving-shaftl by means of the beveled gear-wheelon said shaft and beveled gear wheel on the main shaft, and

the .motion is transmitted from the main shaft through the main gear-wheel to the intermediate gear-wheel, to the intermediate tion is considerably accelerated and trains mitted through the inside gear of said shell and the pinion upon the pressure-shaft to the pressure -shaft. The pressure-shaft terminates in an eccentric-crank pin, from which the fianging-roll, which projects through and revolves in the aperture in the boiler-head on plate, directly and immediately receives rotary motion. In the beginning of the flan ging operation the axis of the flanging-roll, eccentriecrank pin, and main shaft practically coincide. During the progress of the operation, however, the eccentric-crank pin gradually but continually shifts its axis with reference to that of the main shaft, produc ing similar changes in the axis of the flanging-roll with reference to that of the main shaft, and thus, while traveling a constantlyincreasing circle or orbit around the axis of the main shaft, it is impelling or forcing the Hanging-roll against the metal to be flanged. \Vhen the fianging operation has been completed, as above described, the operator disengages the clutch on the shell from the corresponding one on the back gear-wheel, and its own weight, or, if necessary, that of the counter-weight attached to the clutch-lever, forces the female part of the friction-clutch formed by the conically-shaped extremity of said shell upon the male part of said frictionclutch formed by the conically-shaped part of the bearing of the main shaft, thereby arresting the rotary mot-ion of the shell and pressure-shaft and enabling the main shaft, which is meanwhile revolving, to make about one-half of a revolution requisite to bring the main shaft, pressure-shaft, and flanging-roll into the positions relatively occupied by each at the beginning of the flanging operation. Before the projections upon the shell and main shaft respectively come in contact the spirally-inclined upper surface of the main shaft projection, moving along the corresponding lower surface of the shell projection, gradually elevates said shell sufficiently to release it from the friction-clutch. \Vhen the projections upon the shell and main shaft engage, the shell is carried (in case the machine is permitted to run) along with the main shaft without changing the relative positions of the main shaft, pressureshaft, and Hanging-roll until the shell is again ele vated and clutched by the main gear-wheel.
